PostgreSQL data files are operating system and CPU architecture specific. So first of all your Linux and Windows systems would need to be of the same architecture. And then the data layout that the compilers use would need to be the same as well. I have tried this in the past between Linux and Cygwin, and it did not work. So I would be very surprised if it worked between Linux and native Windows. In general, don't count on it.
